IMPROVEMENT IN POINTS DRIVE-WELLS.

Specification forming part of Letters Patent No. 218,9 1 0, dated August26, 1879; application filed April 3, 1879.

To all whom it may concern:

Be it known that I, ALPHONSO WILsoN, of the city of New York, in thecounty and State of New York, have invented a certain new and usefulImprovement in Points for Drive- Wells, which improvement is fully setforth in the following specification and accompanying drawing, in whichthe figure is a longitudinal section of my improved point for drivewells.

A is the castiron point. B is the perforated section of the tube.

My invention consists in casting the point onto the tube; and the objectof my invention is to obtain strength and cheapness.

To make my improved point for drive-wells I upset the end of the tube,so as to form a rim or flange, O. The tube is then laid in the mold, sothe cast metal will flow all around more pieces of metal together byplacing the cold piece or pieces in the mold and causing the moltenmetal to flow around them is not new, and that I do not claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

An iron point for drive-wells, cast on the tube, substantially as setforth.

ALPHONSO WILSON.
